This invention relates to the construction of frame molds for the production of chocolates, candies or the like.

It is known to construct frame molds for the production of chocolates by inserting individual molds in apertures in a sheet iron plate adapted to form the upper side of the mold and thereupon to connect the individual molds with the plate by solder inserted on the lowerside of the plate.

As distinguished therefrom the new method consists in inserting the individual molds on the plate adapted to receive them, thereafter applying a covering plate of asbestos or heat resisting material and connecting it with the plate for example by clamping and thereupon dipping the mold for a moment in a bath of tin.

As a result all of the individual molds are secured at one time to the plate carrying them without the necessity for separately soldering each of the usually numerous individual molds. The inadequacy of individual soldering is also avoided because by the use of the bath of tin penetration of the connecting means takes place at all necessary points and accordingly also individual molds which do not fit exactly in the corresponding apertures in the plate are secured with sufficient reliability. Moreover, with the use of individual molds of tin plate in consequence of the use of the bath of tin the known burning ofi becomes unnecessary.

The accompanying drawings will serve to assist in the further explanation of the invention.

In the drawings, Fig. 1 is a cross section showing the application and attachment of the asbestos covering plate.

Fig. 2 is a cross section of a mold in which the individual molds have a wide flange and by the assembly together of the individual molds a closed upper surface is formed.

Figs. 3 and 4 show in perspective View from above and beneath a frame mold in which. the individual molds are formed without flanges.

Fig. 5 shows in perspective an individual mold without a flange.

Fig. 6 shows an individual mold with a wide flange.

Fig. 7 shows a row of juxtaposed individual molds with wide flanges.

Referring to the drawings, on the usual iron frame a, which is indicated only in dotted lines, is mounted a sheet iron plate I) of suitable thickness. This plate is formed. with apertures in which the individual molds c which for example may be of tin plate are inserted. These individual molds have a small flange d bent at, right angles by which they are mounted on the plate I).

On the plate b thus prepared is laid a covering plate e of asbestos and thereover for securing purposes is laid a covering plate 1 of metal. All 5 these plates are firmly clamped together temporarily by clamps or. the like.

Then the plates clamped together are dipped for a time in a bath of tin. There is thus formed .on the free, i. e. uncovered, surfaces of the plate b 10 a thin coating of tin g,. the tin also penetrating any gaps between the individual molds and the in these operations. I 25 In this way there is obtained exceedingly quickly a completely reliable junction of the individual molds with the cover plate and namecautions need be taken to ensure that the individual molds correspond absolutely exactly with 30 the dimensions of the apertures in the cover plate. 1

Obviously exactly fitting individual molds with flanges cut with sharp edges, i. e. in which the flange d is absent, may be fitted in the apertures 35 in the plate b.

. Figs. 3 and 4 show in perspective view a mold which has been formed in this way. In this instance the drawn hollow molds c (Fig. 5) without. flanges-are fitted in the plate I). Then the 40 covering plate e of asbestos is applied and over this the covering plate 1. In order to secure the separate plates against displacement they are held together by a clamping device or clamps K. 45

The plates are then dipped in a bath of tin in exactly the same manner as that already described. There is thus formed on the free uncovered side a thin tin coating and the tin penetrates also into the gaps between the individual 50 molds and the aperture in the plate I). A sufliciently reliable connection of the inserted hollow molds c with the perforated plate b is thus produced. Should the tin reach the covered .plate at many parts, these parts can be given a subsequent treatment, such as grinding or the like. In this way all superfluous tin is removed. After the junction of the hollow molds c with the perforated plate I), the unit thus formed is secured on the frame a.

There is described above how in the production of the molds the inserts c with a narrow flange or without a flange are inserted in the perforated plate b. It is however also possible to form the frame molds by leaving a very wide flange on the individual molds and cutting these flanges to rectangular form so that the individual molds appear somewhat as shown in Fig. 6. These individual molds with their edges 71. are so juxtaposed with respect to one another as to form a strip of individual molds as shown in Fig. 7. These strips are not at first firmly soldered but only slightly for example by spot welding. The formation of the strips can also be effected by joining together the individual molds along their short edges h (Fig. 2).

Strips k: are thus formed by connecting the individual molds c. If now a number of strips k are arranged in similar manner to the individual molds c a connected frame mold is formed, the length and the width of which depend on the number of the individual molds c joined to form a strip as also on the number of connected strips k.

The juxtaposition of the individual strips It serves only to provide a preliminary light connection. They are only connected to one another at separate points for example by spot' welding.

The frame mold produced in this way by joining the individual mold parts is now treated in the same manner as is already described The upper side of the plate is covered with an asbestos plate and a covering plate laid thereover. The whole unit is held together by clamps and dipped in a bath of tin. In this bath a'flrm junction of the abutting parts is effected by the tin flowing into the gaps. As the individual molds are treated on their abutting edges a firmly united plate is formed. The passage of the tin from the uncovered side to the covered side during the dipping process is not therefore liable to occur. Should it occur the superfluous tin can be easily removed by subsequent treatment, by grinding or the like.

As the plates consist of a connected unit and not as in the preceding case it is preferable to stiffen them somewhat. This stiffening may be effected by ribs or bars 1 which are fitted at the points where the separate strips k are joined to one another. The mold thus formed from the individual molds c, strips k and bars I is then mounted on the rectangular frame. The frames are connected with the ribs or bars in any convenient way so that the whole mold is given a considerable stiffening. The ribs or bars Z serve not only for stiffening purposes but in the use of the molds they protect the individual molds between them from shocks and stresses which might occur, when several such plates are superposed, or as sometimes happens, when one plate is thrown on to others.

The provision of the frame molds with these bars may be effected after the plate formed of the individual molds is set in the frame a. They are connected with the superposed individual molds by soldering and with the frame by intermediate members which are soldered with it.
